accessorize

This term is primarily used in the context of fashion and personal styling. It describes the act of adding small, complementary items—such as jewelry, belts, scarves, or bags—to a primary outfit to make it more visually appealing or to change its mood (e.g., turning a day look into an evening look).

When used transitively, it focuses on the garment being enhanced (e.g., accessorizing a dress). When used intransitively, it refers to the general habit or action of the person (e.g., she loves to accessorize).

Compared to "decorate," which is a general term for adding ornament to any object or room, "accessorize" is specifically tailored to clothing and personal appearance. It implies a sense of curation and style rather than just adding decoration for the sake of it.
